HOSE-COUPLING.

SPECIFICATION forming part of Letters IEatentNo. 732,497, dated June 30,1903. Application filed April 3 1903. I Serial No. .50,885- (No model.)

To all whom it may concern:

Beit known that LWILLIAM R. AMos, a citizen of the United States ofAmerica, residing at Saxton, in the county of Bedford and State ofPennsylvania, have invented certain new and useful Improvements inHose-Couplers, of which the following is a specification, referencebeing bad therein to the accompanying drawings. 7

This invention relates to certain new and useful improvements inhose-couplers; and the object of the invention is to provide novel andeffective means for easily joining two sections or members of a hosetogether in a quick and efiectual manner.

Briefly described, the invention comprises a female member provided witha receiving box-like flange adapted to receive the flange or head formedon the engaging end of the male member, together with means for holdingsaid members in the locked position.

In describing the invention in detail refer ence is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout theseveralviews, in which Figure 1 is a detail plan view of my improved.hose-coupl'er in the coupled position. Fig. 2 is an end elevation. Fig.2 is a longitudinal sectional View of the members in the coupledposition. Fig. 3 is a rear elevation of the male member. Fig. 4 is acentral longitudinal sectional view of a modified form of my improveddevice in the coupled position.

In the accompanying drawings, 1 indicates the female section or member,and 2 the male section or member, each of which are substantially in theform of a sleeve and receive the respective sections 3 of thehose, whichis held thereon in any desirable or suitable manner. The female section1 is provided with a face-plate 4, which has an angular flange 5 securedthereto by bolts or tapscrews 5, these angular flanges 5 being providedwith grooves 6, which receive the edges of the face-plate 7, carried bythe male 1116111. beror section 2. The face-plate 7 is tapered on itsface, as seen in Fig. 2 and the grooves 6 are tapered correspondingly toreceive the plate 7. The edge of one of the flanges 5 is provided nearthe upper end of said flange with a plurality of ratchet-teeth 8, whichare plates 4 and 2.

adapted to be engaged by the gravity-pawl 9, pivotally secured to theface-plate 7 adjacent to one edge and near the upper end of said plate.As the face-plate 7 is inserted down inposition in the tapered groove 6this gravity-pawl engages with the teeth 8 and locks with the last toothwith which it comes in engagement. In order to effect a water-tightjoint, abutting bosses 10 are formed on the To uncouple the sections, itis simply necessary to release gravity-pawl 9, whereby the plate 8 maybe drawn out of engagement with the angular flanges of the plate 4.

In Fig. 4 I show the same principle of construction; but in lieu of theintegral bosses 10 I form annular recesses 11' and place thereinflexible gaskets 12, which project slightly beyond the face of theplates 4 and 7 and compress against each other, as shown. With this formof construction the locking device will also be employed. To preventthepawl being accidentally disengaged, I will employ, if necessary, aspring or other device to hold this pawl in engagement.

It will be notedthat in the practice of the invention various changesmay be made in thedetails of construction without departing from thegeneral spirit of my invention.

"Having fully described my invention, what I claim as new, and desire tosecure byLetters Patent, is-

In a hose-coupling of the type set forth the combination with a femalemember provided with bosses at its outer end, a face-plate formedintegral with said member, annular flange-forming members removablysecured to the face-plate, said flange members having tapered groovestherein, of a male memteeth to secure the sections in locked posi- 1tion.

In testimony whereof I affix my signature in the presence of twowitnesses.
